socket实例化，并且绑定1000端口，持续进行监听，’0.0.0.0’表示监听本地。sock.listen(backlog)表示可同时监听连接的数量，一般为5。sock.accept()返回(connection,address)，connection通常用来发送和接收数据，address是客户端的Internet地址。conn.recv(2048)进行接收数据，然后conn.send(result)将结果送回给客户端。“`python

socket_client.py

import socket

def socket_send(command):
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((‘192.168.1.55’, 1000))
sock.send(command)
result = sock.recv(2048)
sock.close()
return result

if name == ‘main’:
print socket_send(‘ls’)
sock.connect(address)，里面是一个tuple，IP地址和PORT，发送命令给server，然后用result接收结果并进行return
